nodal head
解釋
節點機座，用於腳架上，使相機、電影機等移動時保持視場穩定，不會產生變形-
The direct optimal model of multi - objective mixed discrete variables for lager - scale water supply system was established, by replacing complicated network hydraulic equation with nodal pressures macroscopic model and relationship model between pump stations flow and head in water supply systems without tanks or towers, genetic algorithm was developed to solve the direct optimal model
以測壓點壓力宏觀模型、水源供水量和水源供水水頭之間的關系模型替代復雜的管網水力平衡方程，建立了大型供水系統的多目標混合離散變量的直接優化調度模型。在沒有水池和水塔的供水系統中，利用遺傳演算法對直接優化調度模型進行求解。 -
A modified svm model was proposed and implicit function relationship between nodal pressures and pump station flow, pump station head was established based on modified svm model
本文提出了一種改進svm演算法，並基於該演算法建立了測壓點壓力和泵站流量、水頭之間的隱式函數關系。 -
You have probably a bad nodal point setting ( position of the camera on the tripod or the panoramic head ) or some distortion in your images
你在你的圖像中或許有一個壞的節點設定（照相機的位置在三腳架或全景的磁頭上）或一些失真。
